The Intel Core i7-640M was a mobile processor with 2 cores, launched in September 2010, at an MSRP of $346. It is part of the Core i7 lineup, using the Arrandale architecture with BGA 1288. Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 4 threads. Core i7-640M has 4 MB of L3 cache and operates at 2.8 GHz by default, but can boost up to 3.467 GHz, depending on the workload. Intel is making the Core i7-640M on a 32 nm production node using 382 million transistors. The multiplier is locked on Core i7-640M, which limits its overclocking potential.
With a TDP of 35 W, the Core i7-640M consumes only little energy. Intel's processor supports DDR3 memory with a dual-channel interface. The highest officially supported memory speed is 1066 MT/s, but with overclocking (and the right memory modules) you can go even higher. For communication with other components in the machine, Core i7-640M uses a PCI-Express Gen 2 connection. This processor features the HD Graphics (Ironlake) integrated graphics solution.
Hardware virtualization is available on the Core i7-640M, which greatly improves virtual machine performance. Additionally, IOMMU virtualization (PCI passthrough) is supported, so that guest virtual machines may directly use host hardware.
